The Kepler space telescope is trailing Earth in its orbit, and has begun scanning its small patch of sky for twinkling stars. It will be a long time before the telescope finds any extra-solar planets, because it relies on planets crossing between Kepler and their stars, causing the stars to dim. To ensure it really is a planet and not some other phenomenon or glitch, it has to watch for several regular transitions. Of course, each planet will cross its star once a year, so these periodic dimmings are few and far between. This means it will be years before the existence of extra-solar planets is confirmed. In other words, the sooner we get started the better. See my previous blog post with professor Mike Thompson for more information.
The new Star Trek movie apparently has some time travel in it. I haven’t seen it yet, and am generally wary of movies that use time travel as a plot device. However, there is a very interesting article about some of the false presumptions of time travel at the Discover website. The article answers a lot of questions that I’d had, and things that I’d puzzled over. Check it out!
Here‘s a good article about one man’s plans to examine the Overview Effect, the feeling of oneness that astronauts get when seeing the Earth from space. Apparently, this happens pretty regularly. I heard one Apollo astronaut (I forget which one) mention the feeling in the terrific documentary In the Shadow of the Moon, but I didn’t know it was such a common phenomenon.
Finally, you’ve got to see this slideshow on the National Geographic website featuring glow-in-the-dark animals.
